In this activity, students write simile's to describe each color of the rainbow. The writing portion can be adapted to fit the skill level of students from Kindergarten through 5th grade. Younger students could just write the colors and/or adjectives and older students could write full descriptive sentences. The rainbow outline is provided. Students can crumble tissue paper and glue on as seen in the picture or you could simply have them color or paint it. I used this for a St. Patrick's day activity and as an introduction to poetry.
